So far I’m very pleased with Mishimoto sandwich plate. Wanted a plate with a thermostat and needed the 23 mm filter adapter. The universal cooler that it’s hooked up with didn’t come with the correct size to fit a FL500 filter. It mounts easy, nicely crafted and seems to do what the discerption says. The plate works great!

I recently purchased this sandwich plate so I could add an oil cooler to my car. I track it regularly and had excessive oil temps in my opinion. 270 plus. I was told by Mishimoto that the sandwich plate offered in the oil cooler kit on this site was not the correct one so I went with this one. Install went smooth and my oil temps are now 210-215 max on hot track days. This product works.

After reading review on oil teps at 3500rpm and above when ford was first testing coyote? I decided to add a oil cooler with the TT kit.
